The expanding Kardashian clan won't have to worry about hiring a babysitter anytime soon. Kim Kardashian's half-sister Kendall Jenner tells Us Weekly that she's excited to be an aunt for the third time, and is excited to spend time with her new, week-old niece North West.

The model revealed that she's even bought a present for Kim and Kanye West's bundle of joy. "I bought a little pig for the newborn," she told Us at the opening of Sugar Factory American Brasserie in NYC on Thursday, June 20. When asked how the new parents are doing, Jenner told reporters that "They're doing great, everyone's good."

"I love kids, so it's so much fun for me," Jenner said of the new addition to the family. "I love hanging out with Mason and Penelope," she said of sister Kourtney Kardashian's kids.

Jenner added that her most famous big sister has given her primo red carpet tips over the years. "Kim always says [to] tilt your jaw down and suck in your teeth to give you a flattering angle," she said, adding that her mom and sisters are "all good advice givers."
